LEANDEB SQULE AND HENRY It. PACKARD, OF TAUN TON, MASS., ASSIGNORS OF ONE-HALF TO THE ALBERT FIELD TACK GOMPAN Y, OF SAME PLACE.

MACHINE FOR MAKING CUT-NAILS.

SPECIFICATION forming part of Letters Patent No. 244,494, dated July 19, 1881.

Application filed December 20, 1880. (ModeL) To all whom it may concern:

Be it known that we,Li1AND11ru SOULE and 2 is a front elevation of the same. Fig. 3 is aplan of the same. Fig. 4. is a vertical section on the line w w of Fig. 3. Fig. 5 is a horizontal section on the line 3 4 of Fig. 4; Figs. 6,7, and 8, sectional details enlarged; Fig. 9, detail in elevation.

In machines for making tacks, nails, &c., as heretofore constructed, it has been found impossible to inclose the entire length of the blank within the griping-dies in order to produce notches or corrugations from one end to the other, as is sometimes desirable, for the reason that a portion of the blank at its larger end (which portion was necessarily held bebeyond the gripingdies, which caused the larger or upper end of the nail to be left plain and smooth, instead of being notched or indented, as required.

Our invention has for its object to overcome this difficulty and to construct a machine in which the entire length of the blank is inclosed within and acted upon by the griping-dies, so as'to allow the latter to notch, indent, or corrugate the entire length of the nail; and our invention consists in making the movable die of the griping-dies in two portions, which are brought successively into contact with the blank, one portion advancing and holding the blank in position between the dies to allow time for the carrier (which carries the blank tion, with a pair of griping-dies having theto describe the manner in which we have carried it out.

In the said drawings, A represents the bed of the machine, to which is pivoted at a a the griping-carriage B, the lever 12 of which is acted upon by a cam, c, on the horizontal driving-shaft O, which runs in bearings in standards rising from the bed A.

dis the bed-cutter, which is secured, as usual, in the block D, and c f are the upper or movable cutters, which are secured to their respective levers E Gr, operated, as usual, independently of each other against the resistance of suitable springs, g h,'by means of cams i 75 on the shaft 0.

H I are the gripi'ng-dies," the stationary or bed die H beiu g secured, as usual, in the block D, immediately beneath the bed-cutter d, Fig. 5, while the movable die I is composed of two separate portions, 1 m, which are caused to act successively upon the nail, as will be hereinafter more particularly described.

K is the carrier, which consists of a long spring-rod secured at 10 to the lever E, its op-. posite end, 12, Fig. 6, which isbent at a right angle, lying immediately beneath the leading cutter e, in order that the large end of the blank may be held between this cutter and the bent end of the carrier, and thence carried, as usual, by the downward movement of the cutter a into a position opposite the scores or grooves of the griping-dies. As soon as this has been accomplished the portion 1 of the die I, which slides in a guideway, n, on the carriage B, is advanced just sufliciently to hold the blank securely in place between it andthe die H, which movement is effected by means of .a lever, 19, pivoted to the lever b, and actuated by a cam, g, on the shaft (3, the lower end of this lever 19 being provided with an adjustable screw, r, which, at the proper time, is

. brought into contact with the bent end of the portion 1 of the die I and advances it against the resistance of a spring, 8. A pin or projection, t, on the shaft 0 now strikes the inclined end of a lever,L, pivoted at 15 to a projection on the lever E, the lower end of this lever L being thus caused to move the carrier K laterally, so as to withdraw its bent end 12 out from between the griping-dies, after which it is allowed to rise with the cutter eand spring back laterally into its normal position, the pin t having passed out of contact with the lever L. The carrier being now out of the way, the other portion, m, of the die I, which is secured in place by screws to o, is then advanced by the forward movement of the carriage B until its end is even with the end of the portion Z(previously advanced) and in contact with the blank, when a set-screw, w, on the carriage comes into contact with the bent end of the portion Z of the die I, as seen in Fig. 5, when both portions of the die are advanced together to withdraw the screw 1' from the bent end of the portion 1, and thus allow the latter to slide in its guideway at until the screw to is brought into contact therewith, which device allows the portion lof the die to remain stationary during the first part of the forward movement of the carriage B, and insures both parts lm completing their forward movement together, so as to simultaneously compress the nail.

a is an arm secured to and made adjustable on one of the standards, this arm having a hooked end, I), Fig. 9, which fits over the carrier-rod K, and a set-screw c, and by means of this arm and its set-screw the position of the bent end 12 of the carrier with respect to the cutters and dies can be adjusted with the greatest degree of nicety.

The two parts l m of the die I may be adjusted in the direction of their length to compensate for wear or other purposes by means of the screws 1' c w.

M is the header, which is supported in bearings in the sides (1 of a frame, N, which is made adjustable vertically and longitudinally by means of suitable slots and screws, in order that the projecting point or teat e at its front end may be always exactly in line with the score or aperture formed between the griping-dies for the reception of the nail. The opposite end of the header is loosely connected by means of a plate, f, and pin 9 with an arm, h, projecting up from a rock-shaft, P, which is actuated by a pitman, Q, pivoted thereto at i, and at its upper end to a crankpin on the end of the driving-shaft O, which, as it revolves, produces through the connections described and at the desired time a reciprocatin g rectilinear motion of the header M, the projecting teat c of which is thus moved back and forth in .a straight line, which enables it to enter the end of the score between the dies, as seen in Fig. 5, and compress the end of the blank, as required, to give it a square, even, or perfectfinish, and then be withdrawn therefrom without any liability of its being bent or broken, as would occur if the header moved in the arc of a circle, as has hitherto been customary in machines of this description.

- 7a is a set-screw, which passes through the arm h and strikes against the end of the header M, whereby it can be readily adjusted in the direction of its length.

If desired, the bedcutter or either of the dies may be made of several pieces secured immovably together, to facilitate the making of the cutting-edgesor griping ends of anydesired shape.

The above-described machine is sim-plc,-durable, and effective, and not liable to get out of repair,. and although specially adapted for making shoe or other nails with notches, grooves, or indentations extending from one end to the other, yet it may be used, if desired, for making nails of other descriptions of tacks.

What we claim as our invention, and desire to secure by Letters Patent, is-

1. In a nail or tack machine, the combination, with the cutters, of the stationary and movable griping-dies II I, the latter formed of two portions, I m, adapted to be moved independently of each other and be brought successively into contact with the blank, and then ad vance together to entirely iuclose and simultaneously compress the blank throughout its entire length, substantially in the mannerand for the purpose described.

2. In a nail or tack machine, the combination, with the griping'carriage B and the stationary die H, of the die I, having the portion at secured immovably thereto, and the portion 1, adapted to slide in a guide or hearing, the lever 12, with its screw 1, cam q,screw w, and spring .9, all constructed to operate substantially in the manner and for the purpose set forth.

3. In a nail or tack machine, the combination, with the stationary and movable gripi'ngdies 11 I, the latter formed of two portions, 1 m, adapted to operate as described, of the carrier K, lever L, and pin t, substantially as set forth.

Witness our hands this 6th day of December, A. D. 1880.
